When booting from the Beta 2 CD-ROM, the aacraid driver is not present in
the installer image modules.cgz, module-info, or pcitable files. This is
a new driver, required for Dell PowerEdge on-board and add-in RAID
controllers. The driver is present in the 2.2.16-3 kernel. The module
must simply be added to the various installer types (CD-ROM, hard disk,
and network).
